P

4.4.4.5 Output short circuit P

IEC 62109-1


TRF_IEC62109_1B

Testing is required to be performed on all combina-tions of terminals for the port under consideration,two at a time, including neutral and earth terminals,and one test with all current-carrying terminals ofthe port shorted together at once.

(1) Grid output

(2) Battery output

(3) Load output

Above three combinations ofoutput terminals are testedone a time.

The AC output short-circuitcurrent is 319Apeak impulse(0.7ms, duration) when singlefault (1) was applied.

The battery output short-circuitcurrent is 950Apeak impulse(2.2ms, duration) when singlefault (2) was applied.

The load output short-circuitcurrent is 45.8Apeak impulse(164.5ms, duration) when sin-gle fault (3) was applied.

P

the short-circuit currents are to be recorded and ifthey exceed the maximum rated current of the cir-cuit, the maximum measured current shall be pro-vided in the installation manual for the purpose ofcoordination of overcurrent protection of the exter-nal circuit conductors.

P

4.4.4.6 Backfeed current test P

For equipment intended to be connected simulta-neously to more than one source of supply, eachinput of the PCE shall be tested one at a time, todetermine if hazardous conditions can result fromcurrent from one source of supply flowing into thewiring for another source under fault conditions.

DC (PV and battery) and ACconsider as source of supply.

P

With the PCE operating under normal conditions, ashort circuit shall be applied at the field wiring ter-minals of the circuit under consideration, with all in-tended other sources connected to the PCEthrough the over current protective devices (if any)intended to be present in the installation.

P

4.4.4.7 Output overload P

IEC 62109-1


TRF_IEC62109_1B

Each output of the PCE, and each section of atapped output, shall be overloaded in turn, one at atime. The other windings are loaded or not loaded,whichever load condition of normal use is less fa-vorable. Overloading is carried out by connecting avariable resistor across the winding. The resistor isadjusted as quickly as possible and readjusted, ifnecessary, after 1 min to maintain the applicableoverload. No further readjustments are then permit-ted.

P

If over-current protection is provided by a current-sensitive device or circuit, the overload test currentis the maximum current which the over-current pro-tection device is just capable of passing for 1 h. Ifthis value cannot be derived from the specification,it is to be established by test. Before the test, thedevice is made inoperative or replaced by a linkwith negligible impedance.

N/A

For equipment in which the output voltage is de-signed to collapse when a specified overload cur-rent is reached, the overload is slowly increased tothe point of maximum output power before the pointwhich causes the output voltage to collapse.

P

In all other cases, the loading is the maximumpower output obtainable from the output.

Note:

For isolated inverters, shall indicate a fault in accordance with 13.9 (operation is allowed); the fault indicationshall be maintained until the array insulation resistance has recovered to a value higher than the limit above

For non-isolated inverters, or inverters with isolation not complying with the leakage current limits in theminimum inverter isolation requirements in Table 30, shall indicate a fault in accordance with 13.9, and shallnot connect to the mains; the inverter may continue to make the measurement, may stop indicating a faultand may connect to the mains if the array insulation resistance has recovered to a value higher than the limitabove.

It is not required to test all PV input terminals if analysis of the design indicates that one or more terminalscan be expected to have the same result, for example where multiple PV string inputs are in parallel.
